WASHINGTON (AP) — The Trump administration is on the verge of gutting one of the United States’ biggest efforts against climate change. The administration is expected to announce a final rule Tuesday that rolls back ambitious Obama-era mileage standards. The Obama administration had set the tougher mileage standards to encourage production of electric cars and more efficient gas and diesel vehicles. Tailpipe exhaust is a major contributor to climate changing emissions. The Trump administration argues relaxing mileage standards will save automakers the cost of new emissions technology, and make vehicles cheaper for Americans to buy. But opponents say Americans will spend far more on fuel than they save on purchase costs.
